ACID-BOTTLE GAGE FOR FIRE-ExTlNG-m uns.

Specification of Letters Patent. Patented March 31, 1908.

Application filed April 30, 1906. Serial No. 314,534.

To all whom it may-concern:

Be it 'known'that I, JosEPH M. MILLER, a

the acid bottle.

, Chemical fire extinguishers of the class to which this inventionrelates, usually consist of a casing or tank having an opening at itsupper end and containing a liquid suitable for fire extinguishingpurposes. A bottle containing an acid or chemical is supported in afixed position in the upper part of the casing with its mouth spacedaway from the cap which closes the casing, the mouth of the bottle beingusually closed by a loose cap. The liquid in the casing also contains anagent which, when mixed with the chemical in the bottle, causes a rapidformation of gas, the pressure of which is used for discharging theliquid from the casing. The mixing of these chemicals is usuallyaccomplished by inverting the casing and permitting the chemical in thebottle to How out.

The main objects of this invention are to provide a simple and improvedform of cage for supporting the acid bottle in fire extinguishers ofthis class, and to provide a construction for such cages which willpermit I the bottle to be readily inserted or with drawn from the cage,to be supported in a fixed position within the casing, to be readilyremoved from or inserted in the cage without withdrawing the cage fromthe casing, and to provide a resilient form of clip capable of holding abottle in a partly lifted position in the cage for convenience infilling the same. I accomplish these objects by the device shown in theaccompanying drawings, in which:

Figure l is a side elevation, partly broken away, of an acid bottle cageconstructed y according to this invention, the casing of the partlybroken away.

fire extinguisher being shown in section and Fig. 2 is a side elevationof the cage showing the bottle supported in a partly lifted position.Fig. 3 is a perspective viewof the cagewith the bottle re,

moved.

In the construction shownin the drawings, the casing 1 of the fireextinguisher is provided at its upper end with an openin or throat-2'having a threaded neck 3. he cap of the fire extin uisher, which closes.the opening 2 is of well own constructionend is not shown in the drawins. The ihterihr.

of the neck 3 is provided with a pluralityof lugs 4 which form shouldersfor supporting the bottle holder or cage. The cage -con-' sists of aring 5 which is of suitablesize to fit within the neck and rest upon thelugs 4. A bottom 6, is secured in parallel relation with the ring 5 andis ri idly connected therewith by a pair of uprig t side supports.

7 which are fastened to the bottoni at opgosite ends of one of the armsthereof. spring clips 8 formed of resilient wife are rigidly fastened tothe opposite ends of the otherarm of the bottom 6 and extend upwardly soas to provide a ca e for confining an acid bottle 9 bet-ween saidvertical wires when seated upon the bottom 6. The clips 8 are bentinward at 10 near their upper ends so as to extend over the shoulder 11of the bottle and support the samewhen the casing is inverted.

The clips 8 are bent outwardly above the bends -10 so that they willspring outward to permit the bottle to be inserted into position.

The usual loose cap 12 is provided for closing the neck of the bottleand has the shank 13 which extends into said neck to prevent the capfrom falling out oi -place when the extinw guisher is inverted or turnedon its side. l

The operation of the device shown is as follows: The bottle is insertedinto the ca e by passing the same downward through t e ring 5 andpushing it down .until the clips 8' engage its shoulder and hold itfirmly H1 positlon. The yielding structure of the clips 8 causes thesame to hear u on the bottle to prevent its rattling, and a so toaccommodate themselves to variations in the. size of the bottles. iVhenthe casing 1 is inverted after its outer cap has been screwed intoplace, the bottle is supported by the clips 8 so that the cap ll? of thebottle will fall away from the mouth sufliciently to permit the fluidcontents of the bottle to run out and mix with those of the casing.

For convenience in filling the bottle, -it may be artly lifted from thecage and will be held 3 the clips 8, inasuch osition, as shown in Fig.2. '1 his permits it to be filled without entirely removing it from thecage. A further advantage of this partly lifted structure is that thebottle may be removed or held in a partly lifted position or replaced.into the cage without the removal of the cage from the casing. Thisfeature .is of great "advantage to the persons who refill the bottlewith acid-in that it reatly reduces the amount ofhandling of the ottleand reduces the liability of getting acid upon the'hands.

What I-claim as my invention and desire ,to ,s'ecure by Letters Patentis:

In a fire extinguisher,- the' combination of a casing having an u wardlyopening neck with an internal seat or 'a'ring, a ring supported onsaidseat, a pair of rodsde endin o'm' thering, a bottom supported y sai'rods, a second rial, having their upper, ends diverging and terminatingbelow and free from said ring,

air of rods of spring mateand each havin an inwardly projectingshoulder, I a bott e adapted to pass freely through said .ringlwhilesaid ring is on-said seat, and being eld upon said bottom by saidshoulders with the bottle mouth upward, said shoulders being adapted toalso support said bottle in a partly Withdrawn position, with its mouthprojecting above the ring; While-said ring is on said seat, and thebottle holder formed of said ring, rods and bottom being adapted to belifted bodily.

from said casing with said bottle. Signed at Chicago this 28th day ofApril 1906.- v JOSEPH MQMILLER.
